Recycling of Lithium Ion Batteries From Electric Vehicles
The recycling of lithium-ion batteries – from EVs and others – will be discussed in this webinar.
Recently, the pilot plant of project LithoRec II could prove that a newly developed combination of process steps enables the recovery of a mass fraction of 75 % and more on a material recycling basis from lithium-ion batteries. This is supposed to be much better than state of the art. Combining different process steps like discharging, dismantling, shredding, sifting and air-jet separation the project partners were able to achieve their goal: proving that lithium-ion batteries can be recycled better. One interesting process dealing with the electrolyte came in a black box (which was actually white) and this was because of another ongoing patenting process of Lion Engineering. A modified and simplified process works to directly recycle scraps from the production of lithium-ion batteries – in order to protect both: the environment and the stakeholder’s money.
This webinar will focus on the following key topics:
• Recycling of Lithium Ion Batteries
• Recycling Yields and how to regain 75% and more – on a material recycling basis
• Direct Recycling of LIB-Production ScrapsPresenter
Christian Hanisch – CEO at Lion EngineeringChristian studied Process Engineering at TU Braunschweig (Germany) and has worked in the research project LithoRec and designed LithoRec II at the Institute for Particle Technology / TU Braunschweig on the topic of Recycling of Lithium Ion Batteries. He developed and patented new recycling processes and led the project to the realization of a pilot plant. Recognizing the highest interest of industrial partners in this topic he co-founded the spin-off Lion Engineering GmbH with fellow PhD students and Professor Arno Kwade in 2011. Beginning in 2016, Christian started to focus full-time on being CEO of Lion Engineering.

Understand and Prevent Battery Fires and Explosions – and Avoid Costly Failures Like the Samsung Note 7
Modern batteries (eg Li-Ion) contain hazardous chemicals & they heat up during use: this combination always has the potential to cause fires & explosions. This presentation will focus on improving the understanding of how these incidents occur, what can be done to avoid them & how the risk can be minimized during early stage design.
The Samsung Note 7 phone & Boeing Dreamliner airplane fires are very costly examples of how even large corporations fail to understand the potential fire risk of batteries.
The solution lies in knowledge of heat generation rate during normal use & information about safe boundaries such as temperature, discharge rate & overcharge, in realistic situations that represent actual use conditions. Data from commercial batteries of different types will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:
• Why battery fires & explosions occur
• How to design safer batteries though understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
• Laboratory instruments suitable for testing and data generationPresenter
Dr. Jasbir Singh – Managing Director at Hazard Evaluation LaboratoryJasbir is a chemical engineer specializing in thermal hazards and calorimetry, traditionally for the chemical industry but now increasingly involved in battery safety, especially Li-ion EV and related types.
A graduate of Imperial College (London), where he undertook PhD into combustion and explosions, his experience includes many years in process design for the chemical and petrochemical industries. He is currently developing test methods and instruments for use in design of battery thermal management systems.

Preventing Li Ion Battery Failures From a Manufacturing and Design Perspective
How can you be proactive and make sure your cell supplier is the right one and you don’t end up with thermal events and field failures? Is it enough to qualify a cell manufacturer according to industry standards? The answer is that the majority of compliance based testing is related to abuse tolerance. However, the vast majority of field failures do not occur under abuse scenarios, but happen under normal operating conditions due to manufacturing flaws or design and system tolerance issues that cause internal shorts. In this webinar, you will learn about common lithium ion battery failure modes and how to be proactive in preventing these.
This webinar will focus on the following key topics:
• Gain an understanding of lithium ion battery failure mechanisms and the pathway to thermal events
• Learn how cell design impacts battery safety and reliability
• Learn the basic steps in a lithium ion cell manufacturing process, and how the process controls affect safety and reliability
• Come away with a checklist to qualify your cell manufacturerPresenter

Avoid Battery Explosions and Fires – With Right Data and Better Designs
Modern Li Ion batteries contain hazardous chemicals and heat up during use – this combination always has the potential to cause fires and explosions. This presentation will focus on improving the understanding of how such incidents occur, what can be done to avoid them and how the risk can be minimized during early stage design.
The solution lies in knowledge of the heat generation rate during normal use, and information about safe boundaries such as temperature, discharge rate & overcharge in realistic situations that represent actual conditions of use. Data from commercial batteries of different types, including videos of batteries undergoing thermal runaway, will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:

• How to design safer batteries through understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
